The application goes back and forth between the travel office and the third-party funding department until both sets of rules agree.

The travel office checks daily allowance, accommodation and means of transport under travel expenses law. The third-party funding department checks the same trip to see whether the project may pay for it, and how much. Each sees the application in turn, and every query sends it back to the start.

2sets of rulesTravel expenses law and the project's funding guidelines apply at the same time.
9expense itemsFrom the flight to the conference fee, each item follows its own rule.
3returnsEvery open item sends the application through both offices once more.

Checking both sets of rules on the same application at once eliminates 45% of returned applications.

The 45% reduction in returned applications is the headline figure recorded for this agent. Travel management does not track it as a metric: the three returns are an estimate based on experience, applied to a conference trip with nine expense items.

Three steps through the process.

Both sets of rules come together in the agent; approving the trip stays with the travel office.

Check the travel application against travel expenses law

The agent checks daily allowance, accommodation allowance, means of transport and incidental costs against the applicable rates. If a justification is missing, for example for flying instead of taking the train, it names that exact item.

Application RS-2026-3308, 9 items, 1 without justification

Match the source of funds on the same application

The agent checks the same items against the funding guidelines of the project paying for the trip. It shows which items the project covers and which would have to come from the core budget.

Project DR-7156 covers 7 items, 2 assigned to the core budget

Pass on both check results with the application

The agent attaches both check results, with their references, to the same application and flags the one missing justification. The travel office and the third-party funding department see the same status at the same time.

What the agent does not do.

It does not approve the trip.

It presents the application with both check results. The travel office signs the approval, and the third-party funding department releases the charge to the project.

It does not verify that the trip was for business purposes.

It records that the conference invitation and programme are attached to application RS-2026-3308. The line manager judges whether the trip was business-related.

It cannot see what someone has paid privately.

If someone pays the conference fee of 640 euros from their own account and submits it later, it lists the item as undocumented until the receipt arrives. Only then does it count in the statement.

The questions that come up before the first meeting.

How quickly is the Travel Expenses Agent ready to use?

A pilot typically runs on your own data within 4 to 6 weeks. The agent connects to your existing systems rather than running as a separate, parallel environment.

Where is the data processed?

EU cloud or private cloud. Processing is GDPR-compliant and models are never trained on your data. Details in the Trust Center.

Where does the figure “45% fewer returned applications” come from?

It is based on experience from comparable projects and process benchmarks, not a commitment. We work out the realistic effect for your organisation during the assessment before the pilot.
